EDWARD NORDSTROM, OF soIoTA, ILLINOIS.

CORN-CULTIVATOR.

SPECIFICATION forming part of Letters Patent No. 628,588, dated July 11,1899.

Application filed Apri15, 1897. smart. 630,895. OdBl-l To all whom itmay concern:

Be it known that I, EDWARD NORDSTROM, a citizen of the United States,residing at Sciota, in the county of McDonough, State of Illinois, haveinvented certain new and useful Improvements in Wheeled Cultivators; andI do hereby declare that the following is a full, clear, and exactdescription of the same, such as will-enable any one skilled in the artto which it pertains to make and use the same.

My invention relates to improvements in wheeled cultivators; and itconsists in the improvements hereinafter described and claimed.

Reference is had to the accompanying drawings, wherein the same partsare indicated by the same letters throughout both the views.

Figure 1 represents a perspective view of myimproved cultivator, andFig. 2 represents a top plan View of the same.

The cultivator is intended to cultivate several rows of growing stalksat the same time. The frame of the cultivator consists of a horizontalbeam A, two outer uprights A, and two inner uprights Aimountedvertically beneath the said horizontal beam A. Spindles l3- for mountingwheels thereon are provided upon the lower ends of the outer uprights A.A pair of shafts O are mounted upon the beam Afor the attachment ofthree horses, the middle horse working between the shafts and thenected, as at d, to the end uprights A, and

D D represent similar plows having their beams pivotally connected, asat 01 to the cross-piece d, rigidly mounted between the inner uprights AE E represent two flat timbers having end spindles e j ournaled inbearings f upon brackets F, rigidly secured upon the rear sides of theuprights A and A the said brackets being stiffened by means ofbrace-rods F. These timbers E, with their spindles engaging themountedupon the other beam, as shown in the drawings.

Standards H, rigidly attached to the beams of the inner plows D, areadjustably connected to the handles H by means of removable bolts orpins, as seen most clearly at h in Fig. 1.

I I represent two bars which are pivotally mounted at t' after themanner of the handles H upon the beams E. At or near the extreme outerends of the said beams, but unlike the handles H, these bars have aforward end extending somewhat beyond the said beams E, and the saidbars are not so long as the said handles.

Standards 1, rigidly mounted upon the outer beams D, are adj ustablyconnected to the rear arms of the bars I by means of removable bolts orpins, as seen most clearly at z" in Fig. 1.

A pair of diagonal bars K are pivotally connected, as at 70, to thehandles H at a point near the connection of the standards Htherewith andare adj ustably connected to the forward arms of the'bars I by means ofremovable bolts or pins, as seen most clearly at it in Fig. 1.

The object of the diagonal connecting-bars K is to put the outer plowunder the control of the plowman, for, as will be seen from inspectionof the drawings, a lateral movement of either of the handles II will becommunicated in a reverse direction to its adjacent outer plow, and thusthe distance between the plows may be varied at-will, the adjustment ofthe bars K permitting of adjustment between the inner and outer plowswhere such permanent adjustment is desired for any reason. It will alsobe seen that vertical movement of the handles H will be communicated tothe bars I, so that all the plows may be raised or lowered or given anextra pressure into the earth by merely operating the handles H in theordinary way.

WVhat I claim as my invention, and desire toesecure by Letters Patent,is- V 1. In a wheeled cultivator, the combination with the frame of thecultivator; of rearwardly-extending brackets upon said frame, providedwith journal-bearings; a rock-shaft journaled in said brackets; aplow-handle pivoted at its forward end to said rock-shaft;

an arm pivoted near its forward end to said rock-shaft; a diagonal barconnected at one end to the forward end of said arm and connected at itsother end to said handle; plowbeams pivotally connected with said frame,and uprights connecting said beams to said handle and said arm,substantially as described.

2. In a wheeled cultivator, the combination With the frame of thecultivator; of a rockshaft journaled in said frame; a plow-handlepivoted at its forward end to said rock-shaft;

an arm pivoted near its forward end to said rook-shaft; a diagonal barconnected at one end upon said arm and connected at its other end tosaid handle; plow-beams pivotally connected with said frame; anduprights connecting said beams to said handle and said arm,

substantially as described.
